A light source device includes a light source module having a light-emitting block, an image analysis part, a duty ratio calculation part, a duty ratio determination part and a signal generation part. The image analysis part extracts representative luminance data of the light-emitting block based on pixel data. The duty ratio calculation part calculates duty ratio data of the light-emitting block based on the representative luminance data. The duty ratio determination part generates determined duty ratio data of the light-emitting block based on the duty ratio data from a first period, and the signal generation part generates a driving signal having a duty ratio corresponding to the determined duty ratio data to drive the light-emitting block.

Method for adjusting pixel data based on the duty ratio history of the backlight in order to compensate for the temperature of the backlight

A display panel driving apparatus includes a user position data output part and a move control part. The user position data output part receives user image data and outputs user position data based on the user image data. The user image data is generated by photographing a user. The user position data is generated by mapping a position of the user to a display panel. The move control part compares a plurality of set area data with the user position data and outputs a move control signal based on the comparison of the user position data and the set area data. The set area data is set to the display panel. The move control signal controls a movement of the display panel.
